dldp authentication-mode
Use dldp authentication-mode to configure DLDP authentication.
Use undo dldp authentication-mode to restore the default.
Syntax
dldp authentication-mode { md5 | none | simple }
undo dldp authentication-mode
Default
DLDP authentication mode is none.
Views
System view
Predefined user roles
network-admin
Parameters
md5: Specifies the MD5 authentication mode.
none: Specifies not to perform authentication.
simple: Specifies the plaintext authentication mode.
Usage guidelines
To enable DLDP to operate correctly, make sure the DLDP authentication modes and the passwords configured on the two ends of a link are the same.
If you do not configure the authentication password after you configure the authentication mode, the authentication mode is none no matter which authentication mode you configure.
Examples
# Configure to perform plaintext authentication and set the password to abc (assuming that Device A and Device B are connected by a DLDP link).
· Configure Device A:
<DeviceA> system-view
[DeviceA] dldp authentication-mode simple
[DeviceA] dldp authentication-password simple abc
· Configure Device B:
<DeviceB> system-view
[DeviceB] dldp authentication-mode simple
[DeviceB] dldp authentication-password simple abc

Parameters
cipher: Specifies a password in encrypted form.
simple: Specifies a password in plaintext form. For security purposes, the password specified in plaintext form will be stored in encrypted form.
string: Specifies the password. Its plaintext form is a case-sensitive string of 1 to 16 characters. Its encrypted form is a case-sensitive string of 1 to 53 characters.
Usage guidelines
To enable DLDP to operate correctly, make sure the DLDP authentication modes and the passwords configured on the two ends of a link are the same.
If you do not configure the authentication password after you configure the authentication mode, the authentication mode is none no matter which authentication mode you configure.

Use undo dldp enable to restore the default.
Syntax
dldp enable [ initial-unidirectional-delay time ]
undo dldp enable
Default
DLDP is disabled on a port, and when DLDP is enabled, a port is blocked immediately upon an Initial-to-Unidirectional state transition.

Parameters
initial-unidirectional-delay time: Specifies the delay time for DLDP to block a port upon an Initial-to-Unidirectional state transition. The value range for the time argument is 60 to 300 seconds. If you do not specify this option, DLDP blocks the port immediately upon an Initial-to-Unidirectional state transition.
Usage guidelines
DLDP can take effect only after you enable it globally and on a port.
When enabling DLDP on a port, you can set the delay time for DLDP to block the port upon an Initial-to-Unidirectional state transition. If the port does not enter the Bidirectional state when the delay time expires, DLDP blocks the port.
Examples
# Enable DLDP globally and on Ten-GigabitEthernet 3/1/1, and then set a delay time of 100 seconds for DLDP to block the port upon an Initial-to-Unidirectional state transition.
<Sysname> system-view
[Sysname] dldp global enable
[Sysname] interface ten-gigabitethernet 3/1/1

Parameters
interval: Specifies Advertisement packets sending interval in the range of 1 to 100 seconds.
Usage guidelines
This command applies to all DLDP-enabled ports.
To enable DLDP to operate correctly, make sure the intervals for sending Advertisement packets configured on the two ends of a link are the same.

undo dldp unidirectional-shutdown
Default
The port shutdown mode is auto mode.

Parameters
auto: Configures the port shutdown mode as auto mode. In this mode, when DLDP detects a unidirectional link, it shuts down the unidirectional port.
manual: Configures the port shutdown mode as manual mode. In this mode, when DLDP detects a unidirectional link, DLDP does not shut down the involved port but you must manually shut it down. When the link state is restored to bidirectional, you must manually bring up the port.
Examples
# Set the port shutdown mode to manual mode.
<Sysname> system-view
[Sysname] dldp unidirectional-shutdown manual
